Site-Specific Response Spectrum Using Probabilistic Seismic Hazard Analysis (PSHA) in the Philippines
Abstract
The occurrence of catastrophic earthquakes is putting so much challenge on the survival of mankind. This certain phenomenon occurs naturally and is unpredictable due to the continuous movements of the tectonic plates. This research aims to develop a site-specific response spectrum curve in the Philippines specifically, in Cagayan de Oro City, Northern Mindanao. Available data from PHIVOLCS and USGS were utilized to get the information of the ground motion records in the Philippines to perform the seismic analysis using the R-Crisis software. This software was used to generate the site-specific response spectrum of all barangays in Cagayan de Oro City adopting the 10% probability of exceedance in 50 years with a return period of 475 years. Results revealed that the site-specific response spectrum of eighty barangays of the study area and reduced into 14 cluster based on their nearest spectral acceleration value have much lower compared to the NSCP/UBC 1997 at same periods. It is concluded that after evaluated and validated by analysis of variance that it has a significant difference. It is recommended that the site-specific response spectrum can be forwarded and validated to the legal authorities for policy formulation adopting the result of the study, to present the developed site-specific response spectra of Cagayan de Oro City in national and International conferences, to conduct future related studies using deterministic method in developing the response spectrum in Cagayan de Oro City.
